Server fails to generate integrations with Open APIs

XMLWordPrintable

      When syndesis-server creates the integration project for an Open API provider integration we run into:

      Integration [cobol-to-xml]: Created project files and starting build
Exception in thread "pool-9-thread-1" java.lang.NoClassDefFoundError: com/squareup/javapoet/MethodSpec

      The missing class is part of the javapoet library which is a transitive dependency of camel-openapi-rest-dsl-generator. Most likely the exclusion of all transitive dependencies in server-controller pom.xml cause this behavior:

      https://github.com/syndesisio/syndesis/blob/master/app/server/controller/pom.xml#L62-L76

      So we need to find another way to resolve dependency issues in server-controller pom.xml.

      This happens only on upstream master at the moment.
